TIRE-FILLING COMPOUND. I

Specification of Letters Patent.

Patented July 6, 1909.

To all whom it may concern:

Be it known that I, Funnels M. lVILLETT, a citizen of the United States, residing at Indianapolis,- in the county of Marion and State of lndiana, have invented new and useful Improvements in Zlire-l illing Com pounds, of which the fUllOWlIlg is a specification. Y

My invention pertains to healing compounds for use in pneumatic or inflated tires such as employed on the wheels of automobiles und other vehicles; and it has .t'or its object to provide a simple, easily prepared and inexpensive compound adapted to he quickly and easily injected into a tire and to remain in a soft or viscous state in the tire so as not to detract from the resiliency or springiness thereof, with the result that the tire is possessed of the advantages com mon to ordinary pneumatic tires but lacks the disadvantages of such tires.

With the foregoing in mind the invention in all of its details Will be fully understood from the followingdescription and claim.

llly novel healing compound. consists of the following ingredients, combined in the proportions stated, viz:

Glue 1% gallons. tlyrup i- 1 gallon. Glycerin M pint. Venice turpentine 1 ounce.

In the preparation of the compound the glue is steeped in Water until it is pliant, and is then Well drained and melted. At

, this time the syrup preferably connnon corn svhi p such used on the liable, is added to and connningled with the glue, and the mixture is cooked for apynoniniatcly one hour; the glycerin and the Venice turpentine being added to the mixture :1. short time, say two or three minutes, before the mixture isremoved from the fire.

The compound may he at intoa tire in any approved manner wit out affecting my inventioi'l. I prefer, however, to use an: un-

der pressure to force the compound into the tire, and this in a slow and steady manner while the com osition is still Warm..- Oi course'belore to tire 13 charged with the compound any punctures that ma in the the are plugged, and provision is made for the escape of air from the tire during the charging thereof Withthe compound. Then when the composition appears at the outlet for air and indicates that the tire is full of the compound, 1 close the said outlet in any suitable manner and put on the desired pressure, The soft or viscous compound placed in the tire as stated will of itself adhere to the tire and consequently there is no liability of the compound moving in the tire and detracting irom the usefulness thereof.

it will he gathered from the foregoing that my novel compound is simple and inexpensive, and is adapted to he manufactured with facility and to be readily injected into a tire without the necessity of employint; an expensive apparatus. It, will also be gathered that when properly added to a tire, the compound Wei hs less than half a corre eponding body otsolid rubber-and hence does not render the tire unduly heavy or detract in an appreciable measure from the resiliency or springiness thereof. I would also have it understood that the cookingof the glue and syrup together in the manner hereinhchne described in detail, is essential to the preservation of the compound in a viscous state in the tire, and'l would also have it understood that experiments have demonstrated that the best results are pr0- duced when the ingredients are combined in the specific proportions hereinbefore specified.

Having described my invention, what- I claim and desire to secure by Lettersdatent, is:

The herein described comdound'for filling tires, consisting of a cooke nuxture of one i and one-hall gallons of glue and one gallon nesses.
